Direct measurements of the mean flow and eddy kinetic energy structure of the upper ocean circuletion in the NE Atlantic
Knutsen, Øyvind; Svendsen, Harald; Østerhus, Svein; Rossby, Tom; Hansen, Bogi (Journal article, 2005-07-19)The upper ocean circulation in the sub-polar northeast Atlantic has been a challenge to quantify due to strong and variable wind-forcing, and strong and variable deep currents that lead to large uncertainties in the use ... -
The Iceland-Faroe Slope Jet: a conduit for dense water toward the Faroe Bank Channel overflow
Semper, Stefanie; Pickart, Robert S.; Våge, Kjetil; Larsen, Karin Margretha H.; Hátún, Hjálmar; Hansen, Bogi (Journal article; Peer reviewed, 2020)Dense water from the Nordic Seas passes through the Faroe Bank Channel and supplies the lower limb of the Atlantic Meridional Overturning Circulation, a critical component of the climate system. Yet, the upstream pathways ... -
The Iceland–Faroe inflow of Atlantic water to the Nordic Seas
Hansen, Bogi; Østerhus, Svein; Hátún, Hjalmar; Kristiansen, Regin; Larsen, Karin Margretha Húsgarð (Peer reviewed; Journal article, 2003-12)The flow of Atlantic water between Iceland and the Faroe Islands is one of three current branches flowing from the Atlantic Ocean into the Nordic Seas across the Greenland–Scotland Ridge. By the heat that it carries along, ... -
Intermediate water from the Greenland Sea in the Faroe Bank Channel : spreading of released sulphur hexafluoride
Olsson, K. Anders; Jeansson, Emil; Anderson, Leif G.; Hansen, Bogi; Eldevik, Tor; Kristiansen, Regin; Messias, Marie-José; Johannessen, Truls; Watson, Andrew J. (Journal article, 2005-02)The Faroe Bank Channel is the deepest passage for dense water leaving the Nordic Seas into the North Atlantic. The contribution to this part of the Greenland-Scotland Overflow by intermediate water from the Greenland Sea ... -
Measured volume, heat, and salt fluxes from the Atlantic to the Arctic Mediterranean
Østerhus, Svein; Turrell, William R.; Jónsson, Steingrímur; Hansen, Bogi (Journal article, 2005-04-07)The flow of warm and saline Atlantic water towards the Arctic crosses the Greenland-Scotland Ridge in three current branches. Since the mid 1990's, extensive monitoring with quasi-permanent moorings and regular CTD cruises ... -
Observations of highly regular oscillations in the overflow plume downstream of the Faroe Bank Channel
Geyer, Florian; Østerhus, Svein; Hansen, Bogi; Quadfasel, D. (Peer reviewed; Journal article, 2006-12-23)The Faroe Bank Channel (FBC) is the deepest connection between the Atlantic Ocean and the Nordic Seas. This work describes the dynamic properties of the plume of dense overflow water descending from the Faroe Bank Channel ...
